.SH DESCRIPTION
.sp
.LP
The \fBgss_inquire_mechs_for_name()\fR function returns the set of mechanisms
supported by the \fBGSS-API\fR that may be able to process the specified name.
Each mechanism returned will recognize at least one element within the internal
name.
.sp
.LP
Some implementations of the \fBGSS-API\fR may perform this test by checking
nametype information contained within the passed name and registration
information provided by individual mechanisms.  This means that the
\fImech_types\fR set returned by the function may indicate that a particular
mechanism will understand the name, when in fact the mechanism would refuse to
accept the name as input to \fBgss_canonicalize_name\fR(3GSS),
\fBgss_init_sec_context\fR(3GSS), \fBgss_acquire_cred\fR(3GSS), or
\fBgss_add_cred\fR(3GSS), due to some property of the name itself rather than
the name-type. Therefore, this function should be used only as a pre-filter for
a call to a subsequent mechanism-specific function.
.SH PARAMETERS
.sp
.LP
The parameter descriptions for \fBgss_inquire_mechs_for_name()\fR follow in
alphabetical order:
.sp
.ne 2
.na
\fB\fIminor_status\fR\fR
.ad
.RS 16n
Mechanism-specific status code.
.RE

.sp
.ne 2
.na
\fB\fIinput_name\fR\fR
.ad
.RS 16n
The name to which the inquiry relates.
.RE

.sp
.ne 2
.na
\fB\fImech_types\fR\fR
.ad
.RS 16n
Set of mechanisms that may support the specified name.  The returned \fBOID\fR
set must be freed by the caller after use with a call to
\fBgss_release_oid_set\fR(3GSS).
.RE

.SH ERRORS
.sp
.LP
The \fBgss_inquire_mechs_for_name()\fR function may return the following status
codes:
.sp
.ne 2
.na
\fB\fBGSS_S_COMPLETE\fR\fR
.ad
.RS 22n
Successful completion.
.RE

.sp
.ne 2
.na
\fB\fBGSS_S_BAD_NAME\fR\fR
.ad
.RS 22n
The \fIinput_name\fR parameter was ill-formed.
.RE

.sp
.ne 2
.na
\fB\fBGSS_S_BAD_NAMETYPE\fR\fR
.ad
.RS 22n
The \fIinput_name\fR parameter contained an invalid or unsupported type of
name.
.RE

.sp
.ne 2
.na
\fB\fBGSS_S_FAILURE\fR\fR
.ad
.RS 22n
The underlying mechanism detected an error for which no specific \fBGSS\fR
status code is defined.  The mechanism-specific status code reported by means
of the \fIminor_status\fR parameter details the error condition.
